Sample Application

A test engineer uses Series 988s to control the temperatures of severalautomated test chambers. His computer is linked to the controllersthrough its EIA/TIA-422 serial communications port. His computer pro-gram monitors the temperatures of the chambers and initiates automatictest sequences when certain program parameters are met. After complet-ing a sequence, the computer loads the next temperature to the controller.The computer periodically interrogates each controller for its process tem-perature, set point and alarm status. This information is stored on a diskto provide test verification data for the completed products.
